In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8600 GT 512MB GDDR3 are significantly better than the AMD Radeon HD 2600 Pro.

The HD 2600 has a 60 MHz higher core clock speed than the 8600 GT, but the 8600 GT has 8 more Texture Mapping Units than the HD 2600. As a result, the 8600 GT exhibits a 3.8 GTexel/s better Texture Fill Rate than the HD 2600. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 2600 has a 60 MHz higher core clock speed than the 8600 GT, but the 8600 GT has 4 more Render Output Units than the HD 2600. As a result, the 8600 GT exhibits a 1.9 GPixel/s better Pixel Fill Rate than the HD 2600. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 2600 was released less than a year after the 8600 GT, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The 8600 GT has 256 MB more video memory than the HD 2600, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the 8600 GT also has superior memory performance overall.

The 8600 GT has 6.4 GB/sec greater memory bandwidth than the HD 2600, which means that the memory performance of the 8600 GT is marginally better than the HD 2600.

The GeForce 8600 GT 512MB GDDR3 has 32 Shader Processing Units and the Radeon HD 2600 Pro has 120. However, the actual shader performance of the 8600 GT is 43 and the actual shader performance of the HD 2600 is 72. The HD 2600 having 29 better shader performance is not particularly notable, as altogether the 8600 GT performs better when taking into account other relevant data.

The HD 2600 transistor size technology is 15 nm (nanometers) smaller than the 8600 GT. This means that the HD 2600 is expected to run slightly cooler and achieve higher clock frequencies than the 8600 GT.

The GeForce 8600 GT 512MB GDDR3 requires 46 Watts to run and the Radeon HD 2600 Pro requires 35 Watts. We would recommend a PSU with at least 350 Watts for the 8600 GT and a PSU with at least 400 Watts for the HD 2600. The 8600 GT requires 11 Watts more than the HD 2600 to run. The difference is not significant enough for the 8600 GT to have a noticeably larger impact on your yearly electricity bills than the HD 2600.

GPU Mini Review

Mini ReviewGeForce 8600 GT 512MB GDDR3 is one of the many variants of the fast-middle-class GeForce 8600 GT.
On this version, the GPU is equipped with 512MB of standard GDDR3. The architecture allows the use of 512MB, since the GPU's processing power is strong enough and the memory controller is up for the task of processing 512MB. Therefore, the performance is superior to the 256MB version and any other version of DDR2, including 1GB.
However, and due to its architecture limitations, modern demanding games will require reduced settings, even if they don't require more than 512MB of video ram. Very Demanding games like Metro 2033 are only playable at the lowest settings.
Radeon HD 2600 Pro is a middle-class GPU based on the 65nm variant of the second unified shader architecture, R600.
It's based on the RV630 Core and offers 120 Shader Processing Units, 8 TMUs and 4 ROPs a 128-bit memory interface of standard DDR2. The central unit runs at 600MHz and the memory clock runs at up to 500MHz.
Its performance is, overall, below the average and so today's games are only playable at unattractive resolutions and using low (on some) or medium (maybe) presets and DirectX 11 games aren't supported.
